I got my car back from repairs 2 weeks ago (pics coming soon) and was given this sheet of paper from diagnostics.

This is what caught my attention most:

================
DTC Reported
P1490 = Unknown Trouble Code
P0452 = EVAP CONTROL SYSTEM PRESSURE SENSOR LOW INPUT
P0447 = EVAP CONTROL SYSTEM VENT CONTROL CIRCUIT OPEN

Note: Emissions related FAILURE Trouble Codes will appear in Bold and Italics
================

Can someone explain this to me in laymans terms?

Thanks




P.S. Here's the other items on the sheet:

Readiness Test Status Results
Misfire Status = Complete
Fuel Status = Complete
Comprehensive Status = Complete
Catalyst Status = Not Complete
Heated Catalyst Status = Not Available
Evaporative Status = Not Complete
Secondary Air Status = Not Available
AC Status = Not Available
Oxygen Status = Not Complete
Oxygen Heater Status = Not Complete
EGR Status = Not Available

MIL Status
The Malfunction Indicator Lamp is Commanded ON

 

I saw somewhere that the PO452 was related to the fuel pump. Maybe they did not seat it appropriately upon reinstallation?

 

Gas cap not sealing? (loose or bad seal)?

 

Matt, i'll check on that.
itdood, it's a possibility as well.

So basically "EVAP" codes have something to do with the fuel system?

 

I Dunno....I found the codes, but no reference on the fixes except for a blurb on the 452 which referred to the fuel pump...

 

Will have to give those guys a call then - along with the long list of stuff that needs to be corrected <g>

Btw, i noticed the Max doesn't accelerate as well if i mash the gas pedal -could this have something to do with the pump as well?

 

If it is not sealed, it may not be presurizing the lines properly?
